MTL5051 SERIAL-DATA COMMS ISOLATOR

The MTL5051 provides bi-directional serial data communication from a computer system in safe area to instrumentation in a hazardous area. It is used to provide a fully floating dc supply for, and serial data communications to: MTL643, MTL644, MTL646 and MTL647 IS text displays, other IS instrumentation, keyboards or a mouse. It can also be used for data communications across a hazardous area.

Hazardous Interfacing

See MTL640 Series for details of interfacing with MTL643,

MTL644, MTL646 and MTL647 IS text displays.

Across hazardous areas communications mode

The MTL5051 is used in pairs to transfer bi-directional fullduplex

data across hazardous areas, as shown above. Current

switching is used to minimise the bandwidth-limiting effects of

long cables.

Interfacing to an IS keyboard, mouse or other device

Communicating with RS232-level interfaces, such as an IS

keyboard, mouse, etc. is achieved by using one or more

MTL5051 units as required by the device. (TTL level interfaces are

also accommodated by the TTL-compatibility feature of RS232

receivers.) The supply to the IS equipment may be selected to be

either 5V or 12V by switch on top of unit.
